There is provided a digital broadcast receiver for solving various problems regarding a display which arise due to the switching of a mode. For example, there is provided a digital broadcast receiver capable of displaying an emergency alert broadcast by an EAS even when a mode is switched from an OCAP mode to an external input mode. The receiver has a plane management unit for managing a receiver only plane and a download application plane. The receiver prohibits the emergency alert broadcast from being displayed in the receiver only plane when, under an OCAP mode, a download application takes away an EAS function of the receiver, and then permits the emergency alert broadcast to be displayed in the receiver only plane when the mode is switched from the OCAP mode to an external input mode.
